A study of children with comorbid ADHD and anxiety using Cogmed RM and EEG

Background & Aim: Attention-Deficit/Hyperactivity Disorder (ADHD) presents with various combinations of core symptoms (inattention, hyperactivity, and impulsivity) as well as with co-morbidity with other psychiatric disorders. Most studies have focused on the co-morbidity of ADHD and externalizing disorders such as oppositional defiant disorder (ODD) with fewer studies examining the co-morbidity of ADHD and internalizing disorders (e.g., the anxiety disorders). However, most studies have focused on the treatment of ADHD and anxiety separately despite the co-occurrence of ADHD and anxiety being between 25 and 51 percent. The aim of the current study is to assess the treatment of ADHD and anxiety as a distinct co-morbid subtype of ADHD and to assess the impact of Cogmed on working memory and related neuropsychological functions (ie., response inhibition, attentional breadth) in children with ADHD and anxiety
